AC is On, But It's Still HOT! Diagnosing Air Conditioning in Your Car or Truck!

So i found my 2010 honda crv ac not blowing cold. I check the fuse but cant tell if its bad or not. I checked the compressor its still spinning. I put freon and it went straight to red for instructions. Ehat should i do?

in 2010 i bought a 94 previa, didnt have ac, bought new compressor, condenser, drier, all expansion valves, evaporator, and tubing basically replaced the entire thing with help from a shop where i knew the owner. cost me 1200 plus parts, best investment i ever made, still have the van, it started not blowing as cold 12 years later so filled it with one of them cans and it got cold again. has been fine since. ill never own a car with non working ac.

What if your blower is blowing but the switch not light up

Simple to the point..great job

91 dgree summer? I wouldn’t even touch AC button😂

Can you replace JUST the compressor? If it needs to be , is there such a thing of being able to just replace that and have success?

My problem was low engine coolant. As soon as I added engine coolant to the reservoir and the radiator, my AC went back to blowing cold.

do only thing I learned is that I need to see my mechanic to fix this! 😂

this channel is really informative. Thanks! Keep it up!

Ah, so that condenser fan should be coming on immediately when the ac is on and for me I noticed it's not most of the time.
The ac had only been working when driving on highway so I'm assuming that the only time I'm getting cold ac is when the fan comes on for the radiator?? sounds like a relay or fuse maybe as I just replaced the fan resistor.
strange thing is, the fan came on right away last night and blew cold air when I really didn't need it, but today at noon the fan wouldn't come on, so it just blew warm air until I drove around for about 10 mins, then the cold air kicked in quickly.
I'm hoping there's a fuse.

Thanks for sharing the knowledge

Tnkz gd job ❤

I have a 2015 Grand Cherokee, sometimes it is working sometimes not

That steering wheel was incredibly shiny.

Nice Video! If I want to hook up the AC manifold to your car to do some measurements for the pressure, should I purge the blue and read lines from air once I connect them or no need as the air will not get into the system? please clarify thx

Your a weird guy

Lot of salt rust on those vehicles.

My brand new car ac isn't working

Good video 💪🏾

SteveO? Lol

Thank you! I have a small recovering machine but never used it before, so I need a Freon tank or does it have one internally to recover the Freon? My car ac was working poorly a year ago and after changing pressure sensors, and adding Freon, I found out my fan wasn’t working. On a Lincoln Towncar there’s no ac fan as it’s only one fan so it started overheating the engine. A week or so ago, started working poorly again, I checked the amount of Freon that was a little bit low only so I added but went to far and had to remove a little, after that it blows hot air inside! The low pressure aluminum pipes are hot as well. I’ll be checking the fan clogged this weekend but would appreciate any insights here! Thank you folks!

Yes fuses do burn out on their own & DOES NOT mean something is wrong with the vehicle. They do get old and will need to be replaced at some point 👉 👈.

Thanks for the video you guys are great 😊

My Evap hose was Cold I think it didn’t have enough refrigerant

My air conditioning. Compressor is kicking in and out everything seems to be working right but it takes 30 minutes to an hour before it starts cooling. What's wrong with it

The AC on my Toyota Mark X works at certain times only.

At certain times it stops giving cold AC but at other times it’s all ok.

Any idea on the fault?

Hey everyone, My car optra/nubira/ lacetti is 10 years old. For about a year until a month back the AC performance sucked during daytime and was extremely good at night. But for a couple of weeks, it only blew hot air during daytime and nighttime. So, I took it to a car AC repair service. They checked the compressor and said it's good. But they changed the compressor control valve and refilled the gas. And that made the performance of AC like a new car. But all that's only for two days. Now, it's back to blowing hot air 😢. Could someone please tell me what the problem might be? Thank you for your help.

Pls help my Santa Fe 2015 is cooling only at night and at day time while car is not running it blows hot air and while car is moving it starts cooling not that much cool like night.

man fuck this mfka im tryna fix my car ac and first word he say"yo ac not working like mine" like you ain have to be that petty🤣

If a belt pops off you got bigger problems then your ac not working 😂

Why would the pressure be building? Please help

My 2012 scion xb takes like 5 minutes to cool

Could have saved me weeks of frustration in 10seconds had I seen this sooner. Thank you!

Car aircon when it's not moving it's getting cold but when it's moving it's getting hot

Where are you California 🌈🌈🌈🌈

Not sure if my ac clutch is engaging. 02 GMC SIERRA HD 6.0 L. Do you have a way to test to see the clutch engaging and disengaging? Also, do they get stuck sometimes and need a little rap to get freed up?

my ac doesnt blow cold on 90 plus day after sitting in the sun but at night it blows cold, why is this?

Thank u!

I had to replace a leaking accumulator on my 2004 Ford Crown Victoria LX and upon disconnecting the upper AC line to the evaporator core, I had to pull really hard to disconnect it. When I charged my AC with the machine a mist of freon sprayed from the evaporator core housing around the top side line. Does this mean I broke the seal around the line or did I crack the evaporator core inside the housing? Just need to know before I replace the whole evaporator core. 🤦🏻‍♂️

Nice vid! My ac doesn’t work during a hot humid day when i start my car, but after i been driving it on the freeway its start working again, help pls

My ac compressor in my 2003 Cadillac Cts is bad can you guys do a video on replacing it.

Love these videos have been learning alot from you guys. Keep up the great work!

My corolla A/C is working fine, the problem only is it takes 30 minutes or more before you can feel the cold air inside even I set the temperature at 65F. What could be the reason?

BLend doors are common too, especially if blowing cold out some vent and not other

Nice 👍

Haven't had AC in my Jeep for years too expensive to fix ended up bypassing the AC compressor

I like your tip saying that both fans should turn on immediately upon engaging the AC compressor switch..thank you!

Still confused, can you do a video for older Honda Civic? I had my compressor, dryer orings replaced mid May and ac. Is no longer cold but only cool

I just need a new ride
